Embodiment 1

[0041] Use 3-mercaptopropyltriethoxysilane KH-580 to modify polyester fabric and graphene oxide, and react with polyurethane moisture-absorbing and sweat-wicking finishing agent, so that polyester has good moisture-wicking and heat-conducting functions. The specific steps are:

[0042] (1) Finishing agent synthesis:

[0043] Use 5ml of acetone as solvent, 1% dibutyltin dilaurate (DBTDL) as catalyst, 0.01mol PEG-400, 0.02mol isocyanoethyl methacrylate at 80°C for 5 hours with mechanical stirring to obtain polyurethane moisture-wicking finishing agent.

[0044] (2) Fabric pretreatment:

[0045] ① Alkali weight reduction: Prepare 90g / L sodium hydroxide, 5g / L Pingping plus O mixed solution, and carry out alkali weight reduction on polyester fabrics for 45 minutes at 70°C;

[0046] ② Mercapto modification: prepare 5wt% 3-mercaptopropyltriethoxysilane (KH-580) mixed solution of ethanol / water (volume ratio 4:1), pH is 3-4, temperature is 25°C, Put 1 g of alkali-reduced polyester ...

Abstract

The invention relates to a polyester fabric moisture absorption and perspiration and heat conduction finishing method based on click chemical reaction, comprising: preparation of mercapto-modified polyester fabric, preparation of mercapto-modified reduced graphene oxide, preparation of finishing liquid, moisture absorption and perspiration and heat conduction polyester fabric preparation . In the present invention, the pre-treated mercapto polyester fabric, mercapto-reduced graphene oxide and polyurethane moisture-absorbing and sweat-absorbing finishing agent form firm chemical bonds through click chemistry, so that the polyester fabric can obtain good moisture-absorbing, sweat-wicking and heat-conducting properties; it has simple operation , the process is environmentally friendly, energy-saving and high-efficiency, which can greatly improve the wearing performance of polyester fabrics; the prepared moisture-absorbing and sweat-wicking polyester fabrics have no effect on hand feel and strength.

Description

technical field [0001] The invention belongs to the field of functional finishing of polyester fabrics, in particular to a method for moisture absorption, perspiration and heat conduction finishing of polyester fabrics based on click chemical reaction. Background technique [0002] Polyethylene terephthalate, commonly known as polyester, has excellent properties such as good shape retention, low price, high strength, good elasticity, easy washing and quick drying, so it is widely used in various fields. There are many varieties of polyester, which are widely used in clothing fabrics, bedding, outdoor products, decorative fabrics, textiles such as national defense and military industries, and other industrial products. In 1960, the world output of polyester fiber surpassed that of acrylic fiber, and in 1972, it surpassed that of nylon. At present, polyester fiber has the largest industrial scale and usage, and has become the largest variety in synthetic fibers. Its output has...
